do mexican salamanders had already disappeared in the wild world

As of my last update in early 2023, the axolotl (Ambystoma mexicanum), a type of Mexican salamander, is critically endangered in the wild. Their native habitat, which includes Lake Xochimilco and its surrounding canals in Mexico, has suffered from significant environmental degradation due to factors such as urbanization, pollution, and the introduction of invasive species. These factors have led to a drastic reduction in their population.

Despite dire conservation status, the axolotl has not entirely disappeared from the wild, but their presence is extremely limited and precarious. Many organizations and researchers are working on conservation efforts to protect the remaining wild populations and increase their numbers.

In addition to these efforts, axolotls are also commonly bred in captivity for various purposes, including scientific research and the pet trade. These captive populations help ensure the survival of the species and provide a resource for reintroduction efforts when conditions allow.

If you're interested in the most recent status of Mexican salamanders, it would be wise to check with the latest reports from conservation organizations or scientific publications, as the situation can change rapidly.
